Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
Hello,I am working on an IoT security project, where a TPM like STSAFE-A110 is required for signature verification and data decryption. The latter fails with the mentioned chip and the static (non-ephemeral) private key.Setup:X-NUCLEO-SAFEA1 board (w...
Hello,I am trying to start a debug session with STM32CubeIDE v1.11.2 on my board locked on RDP 0.5.I loaded a valid secure firmware which jumps into the non-secure firmware before setting RDP 0.5.I could connect STM32CubeProgrammmer and flash the non...
Hey guys, I want to perform a firmware upgrade over the air. And use a UART to connect to IoT device.I use stm32l431xx and it contains hardware for symmetric encryption. And the host device which sends the binary uses stm32l496 has SBSFU.So I have a ...
STM32 Trusted Package Creator v2.12.0 creates incorrect option bytes which have 8 rows and no "reserved" last row As per AN5054, it should have exactly 9 rows The option bytes csv created from STPC v2.12 This leads to SFI programming failure. Am I mi...
A packet with CRC error has both SUBGHZ_IT_RX_CPLT and SUBGHZ_IT_CRC_ERROR flag set.In stm32wlxx_hal_subghz.c, this leads to both RxCpltCallback() and CRCErrorCallback() being called.https://github.com/STMicroelectronics/STM32CubeWL/blob/main/Drivers...
I have an existing STM32L433 project (CubeIDE 1.8.0) to which I want to add AES functionality via the CMOX crypto stack (https://www.st.com/en/embedded-software/x-cube-cryptolib.html). I am unclear as to where I am supposed to put the .a file, and al...
It seems that 32 bytes (256 bits) is the maximum key size. If so, is there a list of elliptic curves that will work with keys of this size?
Hello guys, how are you?Currently i have an interesting problem happening with my STM32WB5M. I have a project that uses SBSFU alongside with a firmware that uses the BLE peripheral with CPU2 and etc. I don't use the BLE loader, i developed i customiz...
I have made a FUOTA project and I want to add security to it. I found SBSFU but I see that they must connect the ship in order to update it, and that's not what I want.So my question : is it possible to do a FUOTA with a SBSFU example ? is so how ?
Hi, i am looking for a small MCU with ARM trust zone, ROT, SFI and other security features similar to STM32L552.also fast SPI timing req similar to 401 family ( 401 reference only for timing)STM32F401CBU6, does not have the mentioned security feature...
